Enable CONFIG_NFT_MASQ_IPV4 and CONFIG_NFT_CHAIN_NAT_IPV4

[Xiretza]

They're required for 'nat' chains in 'ip' tables in nftables. The respective IPv6 options are already enabled.

Yeah, I have the same issue. A few necessary modules are disabled preventing the use of much of nftables functionality:

$ zgrep '^# CONFIG_NFT_' /proc/config.gz
# CONFIG_NFT_CHAIN_ROUTE_IPV4 is not set
# CONFIG_NFT_CHAIN_NAT_IPV4 is not set
# CONFIG_NFT_MASQ_IPV4 is not set
# CONFIG_NFT_REDIR_IPV4 is not set
